What service is needed at 180,000 miles?

We don't have the information on the scheduled service/maintenance at this present time-but you can check the owners manual for reference what's due at that mileage

First, the, "Check Engine Light", coming on might have more to do with an issue than just a service reminder. The best thing to do first is to go to an Advance Auto or Auto Zone and have them run the trouble codes. They will do this for free and if you have any questions about the codes that come back, we are here to help.

The Manufacturer Recommended Services stop at 120,000 miles. From there you have to consider not only what is listed in the 120,000 mile service but other items like, completely flushing and changing the brake fluid. Some manufacturers may list this, but most don't. I would certainly recommend EVERY fluid be changed with the mileage you have. Inspect all safety items such as;
The Air Bag System which includes the seat belts, (this is an entire circuit that only a certified technician can inspect).
The Anti-Lock Brake System
The mechanical components of the brake system, master cylinder, booster, calipers, emergency brake cables, etc.
Flush and fill the power steering system and inspect all seals, suspension bushings and alignment of vehicle.
Tire rebalance and rotate with alignment.
The fuel system hoses, fittings, safety inertia switch, filter(s), fuel pressure, etc.
All rubber components such as hoses, belts, bushings, boots.
Axle/CV condition
Wheel bearings

There are probably some other, "Over-Mileage" items that may need to be looked at.
It sounds like over-kill, but safety is certainly important and the old saying, "$100 in maintenance will save you $1000 in repairs.", Is very true.

I am also providing you with the manufacturers' suggested Severe use 90,000 mile and 120,000 mile service.
They have an item or two that are not part of the other. Unless you only drive on the highway I would suggest going buy this schedule. Also, by the time the mileage is as high as your car has, the services are the same.
Please note at the top of each list is a, "Labor Hour" estimate. This is the time it should take a dealership or repair shop to performed the services listed.
On items that I first mentioned such as, "Flush and replace the power steering fluid", you will see this listed in the manufacturer service list. Whether you change the fluid or not is a judgment call based on safety, how long you plan to keep the vehicle, etc. When the fluid is drained out and changed it can be inspected for contaminants such as metal particles which indicate the condition of the power steering system. Meaning, if there is metal in the system, something is failing such as the pump, rack and pinion, etc. And just topping off or looking at the condition of the fluid in the reservoir will not give you this level of knowledge of the sytems' condition. The same goes for any of the fluids in the car.

If you have any more questions, I will look for your replay and get back ASAP.

ThIS would be like a 90k mile service. Here is the link for the maintinance chart and just add 7500 mile service intervals to it.

Hope this helps and if you have any questions then let us know.
